3 Claims. (01. 220-18) This invention relates to new and useful improvements in tanks, especially adaptable as containers for milk, cream and the like; and it has been an object of this invention to, construct a tank in such a manner that the latter will prove extremely durable, as the metal of which this tank is made will not, on account of the special features of the construction, be exposed to corrosion.

Another advantage of this invention lies in,

that a tank, as herein disclosed, may be arranged at any suitable place and may, as it is embedded in concrete, be given permanency of location at a place thought most convenient- With the above and other objects in View, this invention consists of the novel features of construction, combination and arrangement of parts, hereinafter fully described, claimed and illustrated in the accompanying drawing forming part of this specification, and in which similar characters of reference indicate corresponding parts in all views, and in which:

Figure 1 is a perspective top plan view of our device, showing a part broken away, while Figures 2 and 3 are detail views.

Referring more particularly to the drawing, 10' indicates a tank or container that'may be single or double-walled. The said container is surrounded by a concrete mass 11, as shown especially in Figure 1.

of a double-walled container the inner wall 12 and the outer wall 13, connected together in any convenient manner; between these walls suitable insulating materials 14 are arranged. A. concrete mass, as indicated above, is deposited in close proximity to the said outer wall 13, and in order to prevent any moisture from gathering between the said concrete mass, and the outer wall, means has been provided for tightly sealing the junction between these two parts. The said means consists of a lip 17, which is formedby an elongation of the horizontal flange terminating the inner wall member 12 and overlappingv the outer member 13; the said elongated part being in turn bent upon itself, as shown at 18 in Figures 2 and 3.

It will be evident that by such an arrangement the said elongated part or lip, with its double bent portion will prevent any water or moisture from penetrating from above or gathering between the outer wall of the container and the concrete mass,- with the devastating efiect of gradually separating the said concrete mass from close contact with the container and thus in time expose the latter to corrosion and decay.

The usual outlet indicated by 15 is formed in the said container, while the latter may be wholly c The container may be made of any suitabler material, preferably steel, and comprises, in case.

or partly surrounded by a coil wiring system 16 for cooling purposes.

In case a container with a single steel wall should be decided upon, as such an arrangement is quite feasible under the present invention with its compact sealing arrangement, then the insulating materials will be placed directly between the said single wall, or the inner wall, as shown in thedrawing, and the wall of the cache, as

formed by the concrete mass; with adequate cooling arrangement the insulating materials may in this case even be omitted.

It is obvious that changes may be made in the form, construction and arrangement of the several parts, as shown within the scope of the appended claims, without departing from the spirit of the invention, and we do not therefore wish to limit ourselves to the construction and arrangement shown and described herein.

What we claim as new, and desire to secureby Letters Patent of the United States, is:

1. A tank, comprising, in combination, two walls, insulating materials arranged between the said walls, a concrete mass closely abutting upon the outer wall, the inner wall being formed with an elongated horizontal flange, the latter extending over the insulating material, the outer wall and the immediate neighboring part of the concrete mass, the said flange having a substantially U-shaped lip-portion for sealing the junction between the outer wall and the said concrete mass, substantially as shown and described.

2. A device of the class described, comprising,

in combination, a container formed with a bottom outlet therein, and a coil wiring connected to the said container, the latter being formed with an inner and outer metal wall, an insulating material disposed between the said Walls, a concrete mass closely abutting upon the outer wall, the upper part of the inner wall being bent upon itself to'form aflange, the latter extending over the outer wall and the neighboring portion of the concrete mass,'and being formed with a substantially U-shaped bend for sealing the junction between the said outer wall and concrete mass.

3. A device of the class describedbomprising,

in combination, acontainer formed with a bottom outlet. therein, the said container having a wall surrounded by insulating material, and a concrete mass closely abutting upon the latter, the upper portion of the said wall'being bent upon itself to form a flange, the said flange being elongated and extending over the insulating material and the immediate neighboring portion of the con crete mass, and a substantially U-shaped bend upon the said flange to form a lip for sealing the junction between the insulating material and the
